DNG 1.7 (Camera RAW 16) / JPEG XL / lossy support

[Kadet]

I wonder if this Libraw release brings the support. It is pre release though.

Thanks, but currently always in development, not in release

First of all, thank you for all your incredible work on XnView! It's an indispensable tool for so many of us.

I'd also like to express my interest in support for Lossy DNG 1.7 (JXL) files. I understand this often depends on updates to external libraries like libraw, which can sometimes take a while.

With that in mind, I was looking into it and thought I'd share a potential alternative, just in case it's helpful. The official Adobe DNG SDK provides a high-level dng_render class that handles the entire decoding process. It returns a dng_image object, which gives direct access to the final RGB pixel array. A good working example of this can be found in the dng_validate tool that ships with the SDK.

Of course, this is just a thought, and I completely understand you have your own roadmap and priorities.

Thank you again for considering it and for all your amazing work!
